Abstract

Se describe un dispositivo para surtir un material o artículo, que comprende un miembro de surtido, el cual se mueve bajo la fuerza de un resorte que provee un almacenamiento de energía. Una disposicion de amortiguacion que emplea un medio de humectacion viscoso, tal como grasa, se utiliza para amortiguar el retroceso durante el surtido. En particular, dicha disposicion de amortiguacion se muestra aplicada a un inyector sin aguja que opera por el impacto sobre el piston de surtido.
